<h3>Details</h3>

<p>Some researchers in the early 1970s set out to study whether there is a
&quot;full-moon&quot; effect on emergency room admissions at a mental health hospital. They separated the data over 12 months into
rates before the full moon (mean number of patients seen 4-13 days before the full moon), during
the full moon (the number of patients seen on the full moon day), and after the full moon (mean
number of patients seen 4-13 days after the full moon).
